Naw, I bought the original DS (which I still use on occasion to get a "WTF are you playing on" from anyone who watches me) cause it just came out, and it was new, and I wanted to play SMB64 but broke my own 64.
The DSlite on the other hand, I bought because it was hard to play pokémon on that clunky older model of mine, (not to mention that the original DS took up an entire pocket) so I got one, and to my surprise, I liked it, and I used it alot until...
The DSi came out. Taking advantage of my newfound bundle of money, I bought one of them, not because it's new and shi...Okay, maybe a little because it's new and shiny, but mostly because of the features, and the fact that my DS lite had a bunch of dimples on its touch screen from a previous incident.
Now adays, I use the other two as backup for when my DSi runs out of power and there's no charger in the vincity.
